Months ago I used a pre-charge resistor as recommended by Will Prowse and others . Worked fine. No spark. My question is .... If i ever disconnect or even switch off my batteries for any period of time would I have to use that resistor again because the capacitors have slowly discharged? Why I ask is I recently I had to disconnect my batteries for a few hours. When I plugged my Anderson connector back together I noticed a small spark. Seems crazy to have a quick, safe disconnect and still have to unbolt cables and use that resistor before you can turn things on again. FYI, My system is kinda small (100AH, 24V Growatt)
